GONCENTRATOR.

Application filed March 4,

To all whom it may concern:

Be it known that I, lVi-LLIAM S. STACY, a citizen of the United States, residing at Ashland, in the county of Jackson and State of Oregon, have invented certain new and useful Improvements in Concentrators, of which the following is a specification.

The invention relates to ore concentrating machinery of the type in which the ore is separated by a combined washing andjiggling motion, the concentrates and tailings being carried off through suitable conduits by means of a pumping mechanism.

The drawings illustrate a preferred em bodiment of the invention. However, it is to be understood that in adapting the same to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature of the invention as claimed hereinafter.

In the drawings hereto attached,

Fig; 1 is a side view of an ore concentrator embodying the invention.

Fig. 2 is a top plan view.

Fig. 3 is a vertical longitudinal section.

Fig. 4- is a transverse section on the line 4rd of Fig. 2,1ooking in the direction of the arrows.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

As indicated the machine is mounted upon trucks so as to b readily transported from one place to another. The numeral 1 designates the body of the machine and the same is constructed after the manner of a box or tank so as to contain water and receive the separating mechanism. A chute 2 is located at one end of the body and is adapted to receive the ore and direct the same into a hopper 3 located at one end of the machine and elevated above the body thereof. The hopper 3 extends approximately the entire width of the body 1 and underlaps the delivery end of the chute 2 so as to receive the material therefrom. The chute 2 embodies passages 1 which diverge toward their delivery ends so as to supply the material to the hopper 3 throughoutits length. The chute 2 is mounted upon the body 1 whereas the hopper 3 is mounted upon the shoe or frame 5 of the separating mechanism.

The shoe comprises a suitable frame 5 which is supported by means of hangers 6 Specification of Letters Patent.

which are connected at their lower ends to the frame 5 and are mounted at their upper ends in standards 7 secured to and projecting upward from thebody 1. A pan 8 is disposed beneath the. frame 5 and is trans versely curved, the receiving end of the pan being closed and its delivery end opened. as indicated most clearly in Fig. 3. This nan catches the tailings and other material discharging from the strides of the separating tables. Brackets 8 support the hopper 3 and are connected at their lower ends to the frame 5 and at their upper ends to a cross piece 9 secured to the under side of the hopper and which has its ends projecting so as to overlap the upper reinforced edges of the sides of'the body 1. A transverse shaft 10 is mounted in standards 11 carried by a cross piece 12 secured to the sides of the bhd; l. The shaft 10 is adapted to be driven from a suitable source of power in any well known way and is provided with a crank portion which is connected by means of a pitman 13 to a rod 14 attached to the rear side of the hopper 3. in this manner the shoe and separating mechanism have a jigging orvibratory movement imparted thereto. A rodor bar 15 is connected at one end to the hopper 3 and its opposite end passes loosely through a member 16 and receives buffers 17 upon opposite sides of the member 16' so as to control the jigging motion and prevent undue shock and wear to the moving parts. L

The hopper is closed at its ends and rear and is provided with separating screens 18 and 19 of different mesh. Pipes 20 lead from end portions of the bottom of the hopper to deliver the material to the separating mechanism. By having the front side of the hopper open above the scpa rating screens 18 and 19 large pieces of material will automatically discharge and thereby prevent choking of the hopper.

The separating mechanism embodies two tables which taper throughout their length, as shown most clearly in Fig. 2. Each of the tables comprises a head portion 21, an intermediate portion 22 and a tail portion 23; the head portion. 21 is covered by means of a perforated hood 24 with which the pipe 20 connects. The intermediate portion 22 is studded with pins. The tail portion 23 longitudinally fluted. The separating tables are connected with the shoe so as to vibrate therewith.

Each table has its component parts in the same plane and is adapted to discharge at the rear and sides. The material discharging at the sides of the tables is received in the pan 8 and directed by it to the rear of the tank 1. The material discharging from the rear of the tables is received directly by the tank 1.

A box 25 is disposed upon the inner side of the rear Wall of the body 1 to receive the concentrates :trointhe se 'iarating tables. A tailings box 245 is disposed beneath the rear end oi? the body and a gate 27 controls the delivery 01" the tailings from the body 1 into the box 26. The concentrates from the body 25 are adapted to be drawn therefrom by means of a pump 28 and the tailings from the box 26 are adapted to be drawn off by means of a pump 29. The pumps 28 and 29 are shown as consisting of the rotary type and the material drawn. oil thereby may be deli vered at any determinate point.

The separating lTlOCllitlllSlD is submerged in'ivater contained in the body 1 and when the machine is in operation, a jigging or vibratory movement is imparted to the shoe and attached parts. The material supplied to the chute 2 is delivered thereby into the hopper 3, the small particles passing through the screens 18 and 19 and the particles'too large to pass through the screen 18 automatically discharging. Thematerial passes from the hopper through the pipes 20 to the hooded portionsrof the separating tables,

the ore being disengaged from the earthy matter by means of the pins or studs on the intermediate portion 22 of the separating tables and the metal passing along the grooved portion 23 of the tables and discharging into the box 25. The earthy matter spreads out and discharges from the sides of the tables into the pan 8 andcollects in the bottom of the body 1 from which it is discharged at required intervals by opening the gate 27. The bdxes 25 and 26 are kept clear by means of the pumps 28 and 29.

The pump 28 returns the concentrates by pipe 28 to the front of the machine Where they are delivered to a suitable table. The pump 29 has a pipe 29" for conveying the tailings to a flume or other point of discharge.

The foregoing description and the draw inns have reference to What may be considered the preferred or approved form of my invention. It is to be understood that i may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall Within the scope of the appended claims llavin g thus fully described my invention what I claim as new and desire to secure by Letters Patent is A separator, comprising a frame mounted to receive a reciprocating movement. a plu- .ralit of separating tables mounted on the frame, each having a rear end and side de livery and comprising head, intermediate and tail portions, the intermediate portion being studded with pins only and the tail portion being longitudinally fluted hoods disposed over the head portions of the tables and mounted on the said frame to move therewith. a pan beneath the tables to receive the material discharged laterally therefrom and carried by said frame, a hopper mounted on the frame and located above the said hoods and adapted to receive the material and deliver the same to thehead portions of the separating tables and separating screens in the hopper.

In testimony whereof I aflix my signature in presence of two Witnesses.
